The Maserati Alfieri concept wowed audiences at its 2014 Geneva auto show debut, helping the Italian brand celebrate its 100th anniversary in style.

However, the Alfieri wasn't just a bit of auto show bling as a few months later Maserati confirmed the car for production, providing a tentative deadline of 2018.

It’s now likely Maserati will miss that deadline, perhaps by a couple of years.

Speaking with Autocar, Giulio Pastore, the person in charge of Maserati’s European division, said key decisions on the platform and final look of the car are yet to be taken. The British publication reported that the decisions might not be made until 2018, which means production isn’t likely to start until 2020—at the earliest.

Pastore revealed that Maserati would instead focus on the launch of a new GranTurismo, along with a new GranTurismo Convertible. Under the previous plans, the GranTurismo Convertible was to be dropped in favor of a convertible version of the Alfieri-based sports car.

Pastore didn’t say when we’d see the new GranTurismo. The current model made its debut at the 2007 Geneva auto show, though its handsome look has certainly aged well.
